Species Profiles
Betta Fish
Betta splendens
The Betta fish (Siamese fighting fish) is one of the most popular freshwater aquarium fish in the world, known for its stunning flowing fins and vibrant colors. Males are territorial and should be kept alone or with carefully chosen tank mates. Despite their reputation as low-maintenance fish, bettas thrive best in heated, filtered tanks of at least 5 gallons.

Hyphessobrycon eques
Serpae tetras are vibrant blood-red schooling fish with a distinctive black comma-shaped marking behind the gill plate. While beautiful, they have a reputation as fin nippers — especially in small groups. Keeping them in schools of 8+ in a spacious tank significantly reduces this behavior. They add bold color to community tanks when kept properly.
